ACHARLES F. PIKE, OF PHILADELPHIA, PENNSYLVANIA.

OREWASHER OR CONCENTRATOR.

` SPECIFICATION forming part of Letters Patent No. 528,974, datedNovember 13, 1894.

Application filed June 10, 1893. Renewed April 1'7l 1894. Serial No.507,939. (No model.)

o all whomit may concern.-

Beit known that I, CHARLES F. PIKE, a citizen of the United States,residing at Philadelphia, in the county of Philadelphiaand State ofPennsylvania, have invented certain new and usefulImprovements in OreWashers or Concentrators; and I do hereby declare the following to be afull, clear, and exact decription of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has relation to ore washers or concentrators of the formhaving a feed and a suction or forcible discharge; and it has for itsobject to adapt the same to a flume supply for handling economically,thoroughly, and efficiently large bulksof ore or gangue.

My invention accordingly consists of the combinations, constructions andarrangements of parts as more fully described in the specification andpointed out in the claims.

Reference is had to the accompanying drawings, wherein- Figure lisan'elevation partly sectional of a form of washer and a Hume supplyembodying my improvements. Fig. 2 is an end view of rotating screen andits support interposed between the fiume and washer. Fig. 3 is a viewsimilar to Fig. 1, illustrating another form of screen between the flume and washer. Figs. 4, 5, 6, and 7 are sectional elevations of stillother different forms of screens or separators interposed between theume or supply and the washer. Figs. Sand 9 are respectively, a plan andside elevation of a perforated Ahinged bottom for the receiving vesselof a washer of the forms shown in Figs. 1 and 2. Figs. 10 and 1l aresectional elevations partly sectional of additional forms of screens orseparators between the supply and the washer, and Fig. 12 is anelevation showing a modification of separator indicated in Fig. 10.

A in Figs. 1 and 3 represents a form of orewasher or concentrator havingsupply tubes aafor feeding into the washer different grades of ore organgue, a suction or other discharge appliance a', a suitablyconstructed chamber t. n ber a8, and rotating screen B, see more plainlyFig. `2, having different meshes b b constructedand arrangedforoperation substantially as shown, described and claimed in a pendingapplication filed by me of an even date herewith, Serial No. 477,164.

C represents an ore supply chute or flume which may be suitably locatedrelatively to` the feed device c. of the Washer or concentra` tor A asdesired or the demands of service require. In Fig. lits discharge end isshown entering the screen B for the feed devices a a. In Fig. 3 suchflume is indicated discharging into a receptacle c to be hereinafterdescribed while large Waste-matters pass off of its terminal end. Said['lumeis at any suitable location along its length provided with aperforated or other grating or screen c below which is a chamber chaving a pipe connection d with a valve d', with washer A or its chamberas to provide an inflow of water to the washerit having if desiredasuitable overflow pipe f.

The object vof providing the screen c and chamber c with supply pipe dfor the washer is to admit of utilizing a partof the flow-water on thefiume as a supply for the upward or otherwise directed current inchambers c3 and a2 of the washer for agitating the ore or gangue fed tochamber a2 from tubes a a.

In Fig. 3, the rotating screen Bis dispensed with, the large uselessbulky material passing off of the end of the flume at c2 and conveyedaway from the machine by a chute c3. The chamber c is provided with adeflecting partition e and a grating or perforated plate e1 forpreventing any gangue or ore pasisng to the chamber a3 of washer A. Theoutlet pipe dmay lead out from the bottom of chamber c as shown in fulllines in Fig. 3 or from near the top of same as indicated by dottedlines. In the latter case the opening of the outlet pipe d is protectedby a detlecting plate e3.

In Figs. 6, 7, 8, and 9 the flume or supply chute C is shown terminatingin aboX or large receptacle c above the fiume and without screen buthaving a gate or valve c4, and said figures show various ways oflocating and arranging pipe d.

Fig. 12 shows a funnel shaped screen or separator having pipe dattachment, and the box c has a screen and bulky material outlet withyIOO valve c4 for regulating the discharge of gan gue or ore to the feedtubes for the Washer.

From the foregoing it will be noted that the ore or gangue in the Wateron the flume or chute C is conducted to the feed devices a of the Washerand that part of the Water on the fiume which is most devoid of sand isconducted by aseparate pipe d to the chamber a3 of said washer forsupplying the inward and upward current from the outer chamber a, to theinner receiving chamber a2 of the washer for eecting agitation of theore or gangue supplied to chamber a2; that in some of the forms ofconstruction the water from the iiulne for pipe d has more or less ofthe light material of the ore or gangue mixed with it. I prefer howeverthe use of the first above described arrangements or that in which thefeed water from the flume for pipe d is devoid as near as maybe of anysolid matters of the ore or gangue.

AsV it is obvious that the construction and arrangement of the novelfeatures and operations herein described by me may be changed withoutdeparting from the spirit of the in- Vention, I do not confine myself tothe same as shown and described.

l. In combination with an ore washer or concentrator havinga feed deviceand a suction discharge device, of a fiume or chute leading to said feeddevice,` and a pipe connection between the washer and the ilumeor chutefor conducting part of the water on the flume to the Washer foragitating the ore or 3 5 gangue supplied to the washer by its feeddevice, substantially as set fort-h,

2. In combination with an ore washer or concentrator having a feeddevice and a suc tion discharge, of a flume or chute having a valve atits discharge end for controlling the flow of ore or gangue and waterfrom the chute to the feed device for the washer, of a pipe with valvebetween the Washer and the Water level on the flume for providing aseparate water supply from the ume to the Washer for agitating the oreor gangue supplied to it by its feed device, substantially as set forth.

3. In combination with an ore Washer or concentrator having a feeddevice, a fiume or chute C leading to said feed device, a coutrollinggate or valve at the exit end of said fiume, and a conduit leading fromthe water level on the fiume to the Washer or concentrator,substantially as set forth.

4t. In combination with an ore washer or concentrator, a tiume or chuteC having an exit end controlling gate, and connection from above thebottom of said fiume to the Washer or concentrator, substantially as setforth.

In testimony whereof I affix my signaturein presence of two witnesses.

CHARLES F. PIKE.
